Mounting the Power Manager Disk Image
Power Manager is distributed as a disk image. A disk image is a virtual disk that contains a collection of folders and files. To use a disk image, open the file from the Finder. You can double-click the disk image file to open it.
A disk image is ‘mounted’ once it has been opened. The mounted disk image will appear alongside your other devices in macOS’s Finder, much like an external hard disk drive or DVD.
The mounted Power Manager disk image contains the Power Manager application and the latest release notes. Take the time to read the release notes. The notes contain comments about last minute changes or additions to Power Manager. They may also contain specific instructions about the latest distribution of Power Manager.
